One of 15 Saudi men sent to confront Jamal Khashoggi was seen on surveillance video walking around Istanbul wearing a fake beard and the journalist’s clothing after he was killed, CNN reported Monday.

Mustafa al-Madani, allegedly a member of a hit team sent to kill Khashoggi, arrived at the Saudi consulate in Instanbul on Oct. 2 around 11 a.m., CNN said, citing Turkish investigators.

Khasoggi reportedly entered the building at 1:14 p.m. while his fiancee waited outside. Shortly before 3 p.m., surveillance footage recorded Madani exiting the consulate through the back door, along with an accomplice, in the journalist’s blazer, shirt and trousers, CNN reported.

Madani, 57, is of similar height, age and build as Khashoggi, and was likely used as a decoy, Turkish officials told CNN. The surveillance footage captured the Saudi operative donning a fake beard and glasses upon exiting the consulate, which he was not wearing when he arrived hours earlier.

Madani’s role as an alleged Khashoggi body double is the latest in the evolving investigation into the killing. The Washington Post columnist visited the Saudi consulate in Instanbul on Oct. 2 to obtain documents for his upcoming wedding. He never reemerged.
